Good job! I've been doing it for a few weeks now, and believe me it does get easier. I actually hate driving to work now - traffic gets me more worked up when I'm in my car. My commute is similar in length (timewise). I was able to take 15 minutes off my commute just by finding a better route. Beyond that, I've just been keep track of my time and trying to best myself. I've already taken a few minutes off my time just by racing myself. However, there are still some off-days where the legs just aren't as fresh and I go a little slower. It also helps to be late for a meeting - it's amazing how fast you'll find yourself going then...
